Flasher relay for NB1 (1998-2000 pre-facelift). Fits both 1.6 & 1.8 - Does not fit 2000-2004 NB2 (facelift)

If you have no indiactors AND no hazards, this is likely the cause. Also common for them to go bad intermittently, so they may come and go. This is the most common cause.

The part has been updated from Mazda so these aren’t the same as what your MX5 would have come with from the factory, but they are the new genuine direct replacement part. Old number on the unit is BG1P-66-830A
